Abstract

A firearm magazine assists loading of a housing with ammunition. The ammunition inserts into an opening in the top of the housing against a follower. The follower creates tension on the ammunition to direct the ammunition towards the opening. An adjustable plate contacts the spring to load the spring against the follower. The adjustable plate adjusts between a use position and a load position. The use position provides appropriate force to load the ammunition into the chamber. The plate adjusts away from the follower to decrease the tension of the spring and the follower to load the magazine.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A firearm magazine device that reduces tension of a spring on a follower within a magazine, the device comprising:
 an adjustable plate that attaches to the magazine, the plate adjusting between a load position that reduces the tension of the spring on the follower and a use position that increases the tension of the spring on the follower; and 
 a floor of the adjustable plate that provides a surface for placement of the spring to load the spring; 
 an adjustment track wherein the adjustable plate travels vertically upward along the adjustment track against the spring to tension the spring; 
 an attachment finger secured to the adjustable plate that fits within the adjustment track, wherein the attachment finger travels along the adjustment track; 
 an attachment base secured to the magazine, wherein the adjustment track is located on the attachment base; 
 a track opening of the adjustment track, wherein the track opening extends to a bottom edge of the attachment base to allow removal of the attachment finger from the adjustment track at the track opening; and 
 a tether securing the plate to the magazine, wherein the tether attaches to the attachment base and the adjustable plate, the adjustable plate removable from an interior of the attachment base, wherein the tether secures the adjustable plate to the magazine after the adjustable plate is removed from the interior of the attachment base. 
 
     
     
       2. The device of  claim 1  further comprising:
 a tension aperture extending through the attachment base to the floor of the adjustable plate wherein the spring passes through the tension aperture to contact the floor. 
 
     
     
       3. The device of  claim 2  further comprising:
 wherein the adjustable plate adjusts along the adjustment track; 
 a locking position of the adjustment track wherein the locking position limits movement of the adjustable plate away from the follower. 
 
     
     
       4. The device of  claim 3  wherein the locking position of the adjustment track limits movement of the attachment finger away from the follower. 
     
     
       5. The device of  claim 3  further comprising:
 the adjustment track located on an interior of the attachment base; 
 the attachment finger protruding outward from the adjustable plate wherein the attachment finger inserts into the adjustment track to reach a locking position in the adjustment track that limits movement of the plate away from the follower. 
 
     
     
       6. The device of  claim 2  further comprising:
 a blocking foot sized to contact the attachment base, the blocking foot limiting movement of the plate towards the follower. 
 
     
     
       7. The device of  claim 1  further comprising:
 an attachment neck that reduces the size of the tensioning aperture to limit movement of the follower and the adjustable plate. 
 
     
     
       8. The device of  claim 1  further comprising:
 a plate wall extending from the floor towards the follower wherein the plate wall limits movement of the spring. 
 
     
     
       9. A firearm magazine device that reduces tension of a spring on a follower within a magazine, the device comprising:
 an adjustable plate that attaches to the magazine, the plate adjusting between a load position that reduces the tension of the spring on the follower and a use position that increases the tension of the spring on the follower; and 
 a floor of the adjustable plate that provides a surface for placement of the spring to load the spring; 
 an adjustment track wherein the adjustable plate travels vertically upward along the adjustment track against the spring to tension the spring; 
 an attachment finger secured to the adjustable plate that fits within the adjustment track, wherein the attachment finger travels along the adjustment track; 
 an attachment base secured to the magazine, wherein the adjustment track is located on the attachment base; 
 a track opening of the adjustment track, wherein the track opening extends to a bottom edge of the attachment base to allow removal of the attachment finger from the adjustment track at the track opening; and 
 a tether securing the plate to the attachment base, wherein the tether attaches to the attachment base and the adjustable plate, the adjustable plate removable from an interior of the attachment base, wherein the tether secures the adjustable plate to the attachment base after the adjustable plate is removed from the interior of the attachable plate, wherein the attachment finger travels through the track opening to remove the adjustable plate from the attachment base. 
 
     
     
       10. The device of  claim 9  further comprising:
 a tension aperture extending through the attachment base to the floor of the adjustable plate wherein the spring passes through the tension aperture to contact the floor. 
 
     
     
       11. The device of  claim 10  further comprising:
 wherein the adjustable plate adjusts along the adjustment track; 
 a locking position of the adjustment track wherein the locking position limits movement of the adjustable plate away from the follower. 
 
     
     
       12. The device of  claim 11  wherein the locking position of the adjustment track limits movement of the attachment finger away from the follower. 
     
     
       13. The device of  claim 11  further comprising:
 the adjustment track located on an interior of the attachment base; 
 the attachment finger protruding outward from the adjustable plate wherein the attachment finger inserts into the adjustment track to reach a locking position in the adjustment track that limits movement of the plate away from the follower. 
 
     
     
       14. The device of  claim 10  further comprising:
 a blocking foot sized to contact the attachment base, the blocking foot limiting movement of the plate towards the follower. 
 
     
     
       15. The device of  claim 9  further comprising:
 an attachment neck that reduces the size of the tensioning aperture to limit movement of the follower and the adjustable plate. 
 
     
     
       16. The device of  claim 9  further comprising:
 a plate wall extending from the floor towards the follower wherein the plate wall limits movement of the spring. 
 
     
     
       17. A firearm magazine device that reduces tension of a spring on a follower within a magazine, the device comprising:
 an adjustable plate that attaches to the magazine, the plate adjusting between a load position that reduces the tension of the spring on the follower and a use position that increases the tension of the spring on the follower; and 
 a floor of the adjustable plate that provides a surface for placement of the spring to load the spring; 
 an adjustment track wherein the adjustable plate travels vertically upward along the adjustment track against the spring to tension the spring; 
 an attachment finger secured to the adjustable plate that fits within the adjustment track, wherein the attachment finger travels along the adjustment track; 
 an attachment base secured to the magazine, wherein the adjustment track is located on the attachment base; 
 a tether securing the plate to the magazine, wherein the tether attaches to the attachment base and the adjustable plate, the adjustable plate removable from an interior of the attachment base, wherein the tether secures the adjustable plate to the magazine after the adjustable plate is removed from the interior of the attachment base.
